As suggested by Tarte and Cahay,7 (Li2Mn)(SiO4) can
be isostructural to (Li2(4b)Li(2a))(PO4) trilithium phosphate, where
Mn2+ ions are located in the 2a tetrahedral sites within the
[SiO4]4- anionic silicate framework that replaces the [PO4]3-
anionic phosphate framework. The remaining lithium ions
occupy the 4b tetrahedral sites in between silicon and manganese
tetrahedra (Figure 2).
